This article describes the isolation, identification, and characterization of wood-rotting fungi and insects, and their inhibition was studied using gamma radiation. Products manufactured from plantation timber species are deteriorated by wood-rotting fungi such as Hypocrea lixii, Fusarium proliferatum, and Aspergillus flavus, and insects such as powderpost beetles. Proper preservation methods are necessary for ensuring a long service life of wood products. In this study, wood samples were treated with 2.5% copper ethanolamine boron (CEB) (10% w/. v) and subsequently irradiated with gamma rays (10. kGy). It was observed that CEB-treated and gamma-irradiated samples controlled fungi and powderpost beetles significantly. As wood is a dead organic material, penetration of chemicals into it is very difficult. Gamma rays easily pass through wooden objects with hidden eggs and dormant spores of insects and fungi, respectively. Gamma irradiation was proved very effective in reducing damage caused by both fungi and insects. © 2015 Elsevier Ltd.

Lead-free nano crystalline (Na 0.5Bi 0.5) 1-xBa xTiO 3 (BNBT) ceramics with (x = 0.026, 0.055 and 0.065) have been prepared by solid state sintering technique. In BNBT-6.5 resulted in a splitting of the (2 0 0) peak into two peaksof (0 0 2)and (2 0 0) reflections. Splitting in the peak position reveals the composition is well in morphotropic phase boundary region. Average particle sizes have been calculated and found to be in nanometer range. In the energy dispersive X-ray analysis spectrum elements present in the prepared compositions are Na, Bi, Ba, Ti and O only. Impedance (real Z′) plots provide an indication of increasing conduction with temperature andfrequency i.e., negative temperature coefficient of resistance behaviour like semiconductor. The activation energy, E τ is found to be 0.56, 0.88 and 0.55 eV for BNBT-2.6, BNBT-5.5 and BNBT-6.5 respectively; this suggests strongly that theelectrical behaviour of rhombohedral structure in studied materials. BNBT-6.5 ceramics have good properties with piezoelectric constant d 33 = 211 pC/N and electromechanical coupling factors k p = 28 % and k t= 25 %. These high d 33 BNBT materials can be used for transducer applications. The observed dispersion of the imaginarydielectric constant (ε″) is stronger than that of real dielectric constant (ε′). © 2012 IACS.

The objective of this study was to analyze the rainfall variability and trend, and examine vulnerability of fruits production to rainfall variability in Jhalawar district of Rajasthan. A time series data were used to carry out a comprehensive study of the effect of rainfall variability on fruit crops. It was observed that inter-annual and seasonal variabilities of rainfall were major cause of fluctuations in production of fruits in the study area. The district had 910 mm average rainfall with a standard deviation of 218 mm and coefficient of variation of 24 per cent. The annual rainfall as evident from analysis of data (1973-2010) showed negative trend (- 0.23 to - 17.41 mm/year) in the district. Productions of mandarin showed stronger correlations with the post-monsoon rainfall while those of mango, guava, lemon, mosambi, papaya, custard-apple and ber showed strong correlation with pre-monsoon and south-west monsoon rainfall.

Most of the synthetic adhesives used for manufacture of panel products contain formaldehyde as one of the constituents. The Residual formaldehyde in the adhesive gets released during the course of the life of the panel products. The emission of formaldehyde from panels bonded with Urea Formaldehyde resin adhesive has been receiving increasing concern in recent years as it is reported to be a health hazard. At international level, there is lot of restriction on use of panel products which releases formaldehyde above certain levels prescribed by the world health organization. However, in India not much importance was given on these aspects until 2007. Increased public awareness and the consumer demand for non-hazardous products have now resulted as a driving force for the panel industries in India to develop E1 formaldehyde emission class panel products. Facilities have also been established to determine the formaldehyde release from panel products as per European standards. Keeping in view the harmful effect on the end users and environment considerations, studies have been made to develop amino resin system using suitable scavengers that could mop up the free formaldehyde during the resin preparation. © Indian Academy of Wood Science 2012.

Colemanite, also called as hydrated calcium borate hydroxide, is a borate mineral found in evaporite deposits of alkaline lacustrins environments. It is a secondary mineral that forms by alternation of borax and ulexite. As this chemical is not toxic to human beings and other mammals, it has been chosen for the present preliminary work on assessing the efficacy against mould fungi on rubber wood veneers. Colemanite at two different levels of concentrations, 3 and 5 % was tested against moulds and it has been found that 5 % concentration acts as an effective mouldicide. In India this is the first report where colemanite was used against mould fungi. © Indian Academy of Wood Science 2012.

Despite substitution of wood by several other materials like plastics, steel, aluminium etc., wood is still regarded as one of the most versatile raw materials especially in the construction/building sectors. The consumption of industrial wood has risen over the last decade in every region of the world. Also there is a positive correlation between consumption of industrial wood and national income. It has been estimated that the present demand for industrial wood in India is 54 million cubic meters, while the availability is estimated as 30 million cubic meters. To meet the growing need of demand and supply, R&D support is very much needed to provide the acceleration to assure the growth and prosperity of wood and wood based panel industry in future. Wood based panel products industry needs innovative technology solutions that can transform the way traditional wood-derived products are made and enable significant improvements in environmental footprint, manufacturing efficiency and productivity. There are five categories of driving forces which have made impact on the wood and engineered wood product technologies viz., raw material supply, manufacturing costs, product attributes and performance and environment friendly innovative products. Development of formaldehyde and volatile organic compound emission free binder for panel products, formulation of product standards at par with international standards, enhancement of service life of products by treatment with eco friendly preservatives, development of bio adhesives, and fire resistant panel products are some of the priority research areas that need to be investigated. In India, grain and other seeds are the main products of the farming activity and there is great interest in developing uses for residues that are currently burned or ploughed back into the ground. India alone produces more than 400 million tones of agricultural waste annually. Evolving technologies for the substitution of wood by using these non-wood renewable fibers from agro residues and bamboo are another important research area which needs to be worked out to meet the growing demand of panel products. In today's highly sensitive environment, both products and the process have to confirm to certain environmental standards and therefore studies like life cycle analysis, carbon footprints and energy auditing on all next generation engineered wood products need to be investigated. The purpose of carrying out forestry/forest products research today should be to generate benefit for the people by the application of new knowledge generated so far in the field of natural resource management. There is a need for user friendly and problem solving thrust in the field of research, education and extension. © Indian Academy of Wood Science 2012.

A number of recyclable bio-materials are available in India which can be used as raw material base for production of alternate products to wood and wood composites. Bamboo has emerged as a single largest material from which almost all products can be made as is usually made from timber. Perhaps the future generation will use more bamboo based materials due to their availability and versatility than wood and wood products. Besides bamboo, huge quantity of agro and forest residues are available every year in the country. A number of useful products have been developed from rice husk, coconut husk (coir), cotton stalk, bagasse and pine needle. Products made from coir, bamboo, cotton stalk and bagasse are already commercialized in India. © Indian Academy of Wood Science 2012.

Adoption of green concepts in designing of new buildings in India requires energy ratings of the products used. Wood and wood based panel products are still regarded as one of the versatile materials especially in the building and construction sector. However, processing of wood and wood based panel products requires enormous amounts of energy. It is necessary to evaluate these products in terms of energy requirement for raw material procurement and their processing viz., sawing, seasoning, preservative treatment, manufacture and to transport them to a job site. Further, it is also important to consider the upkeep or maintenance of the material after its useful life. Limited research has been carried out in India on embodied energy values of the panel products. Based on the enormous data available around the world, this paper reviews energy consumption of wood based panel products such as plywood, particle board, medium density fibre board and oriented strand board from a building perspective. © Indian Academy of Wood Science 2012.

Investigations were carried out to study the effect of loading methods viz. central and two-point loading on bending properties of panel products made from wood and bamboo viz. plywood, bamboo mat board (BMB) and bamboo mat veneer composite (BMVC). Panel products of different thicknesses were tested under central and two-point bending for evaluating modulus of rupture (MoR) and modulus of elasticity (MoE). The results revealed that there is a reduction of 3-6% in MoE and increase of 6-10% in MoR values for plywood, whereas a reduction of 8-12% in MoE and increase of 6-10% in MoR values for BMVC was observed, when tested by using twopoint loading as compared to central loading method of bending test. Whereas, two-point loading test method is not relevant for flexible panel products like BMB and the values of MoR and MoE obtained by central and two-point loading test methods are not comparable. © 2011 Indian Academy of Wood Science.
